1 Claim. -1

The present invention relates to new-and useful improvements. in applicators, and more particularlyto:a;.device forfdispensing liquid wax, varnish, or other liquid material, to a floor and spreading the same overlthe surface of the floor.

An important object of the invention is to provide a liquid applicator of this character including a container for the liquid and a valve in the bottom'of the "container for discharging the liquid onto a floor, together with a handle for the applicator arranged to actuate the=valve into its open position.

A further object of the invention is to provide a handle control means for the valve in which the handle is pivotally carried by the container and in which the handle is arranged for manipulating the valve when the handle is supported in various inclined positions, thereby enabling the wax to be applied under furniture when the handle is tilted downwardly.

A still further object of the invention is to provide a rotatable and pivotally connected handle for the liquid contain-er, together with means for actuating a dispensing valve carried by the container by a rotary movement of the handle during all positions of its pivotal movement.

A still further object is to provide a device of this character of simple and practical construction, which is efiicient and reliable in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan view.

Figure 2 is a sectional View taken on a line 2-2 of Figure 1.

Figure 3 is a fragmentary vertical sectional view taken on a line 33 of Figure 1.

Figure 4 is a fragmentary side elevational view of the bottom of the device.

Figure 5 is a bottom plan view thereof.

Referring now to the drawings in detail, wherein for the purpose of illustration we have disclosed a preferred embodiment of the invention, the numeral 5 designates a tank or container having a discharge opening or aperture 6 in its bottom and below which is positioned a valve 1 including a valve facing 8 adapted for bearing against the under surface of the container to close the opening 6. The valve 1 is secured to against which. an upper valve l l is -engagedfihe upper valve also including a valve facing d2 adapted to bear against the upper sideof I the top i of i the tcontainer tovclose oneeor mote vent openings-or apertures:t3 therein. h coil spring I 4 vis mounted on: the valve stem s with its lower end xbearing againsttthe bottom =ofthe-container and its uppei en'd bearing-againstithe-under,

side 'o'f the valve-ll to urge the upper'an d lower valvesin-their. closed position.

The upper end of the valve stem 9 is slidable in the top of the container and projects upwardly therefrom and on which is secured an arm 15 supported in spaced relation above the top of the container by the valve stem 9 and formed with a longitudinally curved upper surface I6. The arm I5 is movable vertically between a pair of upstanding guides I! rising from the top of the container.

An inverted U-shaped bail l8 has its lower end pivoted on lugs I9 suitably secured to the sides of the container 5, the central upper portion of the bail having a sleeve 20 welded or otherwise suitably secured thereto.

A handle 2! is rotatably mounted at its lower end in the sleeve 20 and projects below the sleeve with a cam disc 22 secured to its lower end by a pin or the like 23. The cam includes a cam hump 24 which projects from one side of the handle and adapted to ride on the curved upper surface l6 of the arm l5 and to depress the arm and the stem 9 by a rotary movement of the handle 2|.

A coil spring 25 is positioned on the lower portion of the handle with one end secured to a pin 26 carried by the handle and its other end secured to a pin 2! carried by the sleeve 20. The spring 25 is arranged to secure the cam 22 with the cam hump 24 positioned outwardly at one side of the handle and out of engagement with the arm 15, as shown in Figure 1 of the drawings, the cam being movable into engagement with the arm l5 by a rotary movement of the handle against the tension of the spring 25.

A plurality of channel members 28 are secured to the under side of the container 5 and in which the upper edges of felt pads 29 are secured.

The container 5 is adapted to be supplied with a quantity of liquid wax or other floor-coating substance by means of a filler cap 30 in the top of the container and in the operation of the "ranged for engaging the arm IS in any inclined position of the handle and by turning the handle in the sleeve 20 the cam hump 24 will engage the arm I to depress the arm and open the valves 1 and II to discharge a quantity of wax or other liquid onto a floor for spreading over the floor by the pads 29.

It is believed that the details of construction,

manner of use and advantages of the device will be readily understood from the foregoing without further detailed explanation.

It is to be understood, however, that even though we have herein shown and described a preferred embodiment of our invention, the same is susceptible of certain changes fully comprehended by the spirit of the invention as herein described, and the scope of the appended claim.

Having thus described our invention, what we claim is:

In a liquid applicator, a tank for the reception of fluid therein, said tank having an opening in its bottom thereof for the egress therethrough of said fluid, there being a group of vent apertures arranged in alignment with said opening and positioned in the top of said tank, a vertically-disposed valve stem slidably mounted in said tank, a first valve arranged exterlorly of said tank and carried by the lower end of said valve stem for movement toward and away from said opening, a second valve carried by said valve stem and mounted in said tank for movement toward and away from said apertures, resilient means on said valve stem for biasing said first and second valves in bridging relation with respect to said opening and apertures, an arm having a curved upper surface spaced above the top of said tank and secured to said valve stem, a U-shaped bail having its ends pivotally secured to said tank, a sleeve secured to said bail intermediate its ends, a handle rotatably mounted in said sleeve, a cam disc carried by said handle for engagement with said curved upper surface of said arm to thereby actuate said valve stem, and resilient means operatively connected to said handle for biasing said handle and cam disc out of engagement with said curved upper surface of said arm.
